Approved grounding/earthing system manufacturer: PANDUIT B. Approved telecommunications grounding busbar manufacturer: PANDUIT C. Approved rack grounding kit manufacturer: PANDUIT D. Approved retrofit rack grounding kit manufacturer: PANDUIT 1.7 DEFINITIONS A. Bonding The permanent joining of metallic parts to form an electrically conductive path that will assure electrical continuity and the capacity to conduct safely any current likely to be imposed. B. Common Bonding Network (CBN) The principal means for affecting bonding and earthing inside a building. C. Ground/Earth A conducting connection, whether intentional or incidental, by which an electric circuit or equipment is connected to earth, or to some conducting body of relatively large extent that serves in place of the earth. D. Retrofit Rack Grounding/Earthing The application of grounding/earthing products and technology where equipment is already deployed and functioning. 1.8 OVERVIEW A. The purpose of the grounding/earthing system is to create a low impedance path to earth ground for electrical surges and transient voltages. Lightning, fault currents, circuit switching (motors turning on and off), and electrostatic discharge are common causes of these surges and transient voltages. An effective grounding/earthing system minimizes the detrimental effects of these electrical surges, which include degraded network performance and reliability and increased safety risks. B. The grounding/earthing system must be intentional, visually verifiable, adequately sized to handle expected currents safely, and directs these potentially damaging currents away from sensitive network equipment. As such, grounding/earthing must be purposeful in its design and installation. Four issues require special consideration: 1. Although AC powered equipment typically has a power cord that contains a ground/earth wire, the integrity of this path cannot be easily verified. Thus, many equipment manufacturers require grounding/earthing above and beyond that which is specified by local electrical codes, such as the National Electrical Code, etcetera. Always follow the grounding/earthing recommendations of the manufacturer when installing equipment Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 3

14 1.9 WORKMANSHIP 2. While the building steel and metallic water piping must be bonded to the grounding/earthing system for safety reasons, neither may be substituted for the telecommunications bonding backbone (TBB). 3. Electrical continuity throughout each rack or cabinet is required to minimize safety risks. Hardware typically supplied with bolt-together racks is not designed for grounding/earthing purposes. Additionally, most racks are painted. Paint is an insulator. Unless rack members are deliberately bonded, continuity between members is incidental, and in many cases, unlikely. 4. Any metallic component that is part of the data center, including equipment, racks, ladder racks, enclosures, cable trays, etc. must be bonded to the grounding/earthing system. A. The ground/earth system must be designed for high reliability. Therefore, the grounding/earthing system shall meet following criteria: PART 2 - PRODUCTS 1. Local electrical codes shall be adhered to. 2. The grounding/earthing system shall comply with ANSI/TIA-942 and J-STD-607-A. 3. All grounding/earthing conductors shall be copper. 4. Lugs, HTAPs, grounding strips, and busbars shall be UL Listed and made of premium quality tin-plated electrolytic copper that provides low electrical resistance while inhibiting corrosion. Antioxidant shall be used when making bonding connections in the field. 5. Wherever possible, two-hole lugs shall be used because they resist loosening when twisted (bumped) or exposed to vibration. All lugs shall be irreversible compression and meet NEBS Level 3 as tested by Telcordia. Lugs with inspection windows shall be used in all non-corrosive environments so that connections may be inspected for full conductor insertion (battery rooms are an exception where windowless lugs may be used). 6. Die index numbers shall be embossed on all compression connections to allow crimp inspection. 7. Cable assemblies shall be UL Listed and CSA Certified. Cables shall be a distinctive green or green/yellow in color, and all jackets shall be UL, VW-1 flame rated. 2.1 EQUIVALENT PRODUCTS A. PANDUIT shall manufacture all products related to grounding/earthing and bonding for communications systems. There will be no substitutions allowed. 2.2 GROUNDING/EARTHING AND BONDING A. The Telecommunications Grounding Busbar (TGB) in each telecommunications space will be grounded/earthed to the Telecommunications Main Grounding Busbar Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 4

15 (TMGB) located at the service entrance. The gauge of the connecting ground/earth cable, known as the Telecommunications Bonding Backbone (TBB) will follow J-STD-607-A guidelines, as is shown in the table below. Sizing of the TBB TBB Length in Linear meters (feet) TBB Size (AWG) Less than 4 (13) (14-20) (21-26) (27-33) (34-41) (42-52) 1/ (53-66) 2/0 Greater than 20 (66) 3/0 B. The TMGB will be bonded to building steel and grounded/earthed to the electrical service ground according to BICSI TDM Manual and J-STD-607-B guidelines. Local codes may supersede these requirements. In telecommunications spaces with only one rack, the rack jumper cable can be connected directly to the TGB. Cable Sizes for Other Grounding/Earthing Applications Purpose Copper Code Cable Size Aisle grounds (overhead or under #2 AWG or larger (1/0 preferred) floor) of the common bonding network Bonding conductor to each PDU or panel board serving the room. Size per NEC & manufacturer recommendations Bonding conductor to HVAC 6 AWG equipment Building columns 4 AWG Cable ladders and trays 6 AWG Conduit, water pipe, duct 6 AWG 2.3 COMPONENTS, KITS AND HARDWARE A. PANDUIT StructuredGround Grounding System (StructuredEarth Earthing System) kits, components, and hardware shall be used to construct the grounding/earthing system. B. Use PANDUIT GB4 series BICSI/J-STD-607-A telecommunications grounding busbars for the TMGB, which is ideally located at the AC service entrance. Use a PANDUIT GB2 series busbar for the TGB in each of the other telecommunications/equipment spaces throughout the building. Use PANDUIT LCC-W series lugs when connecting conductors to the TMGB and TGB. C. Route the TBB to each TGB in as straight a path as possible. The TBB should be installed as a continuous conductor, avoiding splices where possible. Use PANDUIT HTAP kits, family HTWC, to provide a tap from the TBB to each TGB. When more than one TBB is used, bond them together using the TGBs on the top floor and every third floor in between with a conductor known as a Grounding Equalizer (GE). Use the J-STD-607-A guidelines for sizing of the TBB when sizing the GE (shown in the table above). D. Avoid routing grounding/earthing conductors in metal conduits. If the grounding/earthing conductor must be routed through a metal conduit, bond each end of the conduit to the grounding/earthing conductor. Use PANDUIT GPL series grounding clamps to bond to the conduit, a PANDUIT HTWC HTAP with clear cover Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 5

16 to bond to the grounding/earthing conductor, and a #6 AWG copper conductor to connect the GPL grounding clamp to the HTWC HTAP. 2.4 RACK GROUNDING/EARTHING A. Equipment and racks shall be bonded in accordance with the methods prescribed in ANSI/TIA-942, as is shown in the figure below. Paint Piercing Grounding Washer Aisle Ground Common Bonding Network to Rack Jumper (Alternate Location) Rack Ground Strip Electrostatic Discharge (ESD) Port Standard Equipment Rack Network Equipment Equipment Jumper Common Bonding Network Common Bonding Network to Rack Jumper Figure 1 - Properly Grounded/Earthed Rack (Back of Rack Shown) B. To provide electrical continuity between rack elements, PANDUIT paint piercing grounding washers, series RGW, shall be used where rack sections bolt together, on both sides, under the head of the bolt and between the nut and rack Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 6

17 C. All racks shall utilize a full-length rack ground strip, PANDUIT part number RGS134, attached to the rear of the side rail with the thread-forming screws provided to ensure metal-to-metal contact. D. Mount an electrostatic discharge (ESD) port kit, PANDUIT part number RGESD-1 directly to the rack grounding strip on the back of the rack at approximately 48 inches from the floor. Mount a second RGESD-1 directly to the vertical mounting rail of the rack in the front at approximately the same height. Use the thread-forming screws provided to form a bond to the rack. Place the ESD protection identification stickers directly above the ESD ports. E. When the equipment manufacturer provides a location for mounting a grounding connection, that connection shall be utilized. Use the appropriate PANDUIT RG series jumper for the equipment being installed and the thread-forming screws provided in the kit. F. Use PANDUIT part number RGCBNJ660P (common bonding network to rack jumper) to attach the rack ground strip to the common bonding network. Do not bond racks or cabinets serially. Use the copper compression HTAP that comes with the kit to bond the conductor to the common bonding network. G. Patch panels will be bonded to racks using the PANDUIT bonding screws, part number RGTBS-C for racks having #12-24 equipment mounting holes, and RGTBSM6-C for racks having M6 equipment mounting holes. 2.5 RETROFIT RACK GROUNDING/EARTHING A. If the racks already have network equipment installed, it may not be feasible to install the rack ground strip without disrupting data cables. Further, it may be undesirable to disassemble rack hardware to install paint piercing grounding washers. In these circumstances, the PANDUIT retrofit rack grounding kits, PANDUIT part family RGR, are to be installed. B. For retrofit rack grounding/earthing installations, use PANDUIT part number RGRKCBNJ to ground/earth the rack to the common bonding network. Use PANDUIT part number RGEJ696 (provided with #6 AWG grounding conductor) or PANDUIT part number RGEJ1096 (provided with #10 AWG grounding conductor) to ground/earth equipment chassis to the rack grounding busbar provided with the RGRKCBNJ as is shown in the figure below Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 7

18 Network Equipment Rack Grounding Busbar Grounding Jumper Grounding Jumper Figure 2 - Retrofit Rack Grounding/Earthing C. RGW paint piercing grounding washers are not used in this scenario. Thus, the grounding busbar provides continuity through the vertical channels of the rack, but not the top and bottom of the rack. Thus, wherever practical, the solution using the RGS rack grounding strip and the RGW paint piercing washers shall be used instead of the retrofit rack grounding kits. D. All other grounding/earthing requirements apply to retrofit installations without exception. E. Use PANDUIT STRUCTUREDGROUND Grounding System (STRUCTUREDEARTH Earthing System) in every application possible. See for the latest grounding and bonding solutions. PART 3 - EXECUTION 3.1 GROUNDING SYSTEM The communications grounding system shall be designed and/or approved by a qualified PE, or RCDD. The communications grounding system shall adhere to the recommendations of Grounding Bonding (E) LBUSD Specification 8/25/14 Page - 8

19 the ANSI/TIA-942 and J-STD-607-B standards, and shall be installed in accordance with best industry practice. A licensed electrical contractor shall perform installation and termination of the main bonding conductor to the building service entrance ground.
